1, there is a method you can try. What I saw on TV: lie in bed before going to bed at night, lean your head on the edge of the bed, let your head hang down, and then press your hand along your chin to your earlobe, doing it more than ten times a day. If the brain is congested, you can look up and have a rest, massage your chin with Baubigeat, and then slowly repeat the previous actions when you feel comfortable. If you persist, you can make your chin thin and stiff.
2, don't chew gum at ordinary times, so as not to make your chin fat.
3, open your mouth, the bigger the better, the whole face is elongated, with clean wet gauze, put the next Bala down, and it will be effective in a week. Moreover, if your face is short, you can lengthen it.
In fact, natural beauty is really beautiful, and it is most beautiful to make yourself happy every day.
